Using Logical Operators

Logical operators work strictly with Boolean (that is, True/False) operands. The And operator, for example, is useful for determining if two True/False conditions are both True. Table 4-6 lists the complete set of logical operators that Visual Basic .NET provides.

Table 4-6. Visual Basic .NET Logical Operators

Operator	Mode	Result
Not	Unary	True if operand is False False if operand is True
And	Binary	True if both operands are True False if either operand is False
Or	Binary	True if either operand is True False if both operands are False
Xor	Binary	True if exactly one operand is True False if both operands are True or False
AndAlso	Binary	Same as And but short-circuited
OrElse
